User's Manual

The rate is negotiated between both sides (i.e., the device
adapts to the capabilities of the remote side). Negotiation of
the T.38 maximum supported fax data rate is provided in
SIP's SDP T38MaxBitRate parameter. The negotiated
T38MaxBitRate is the minimum rate supported between the
local and remote endpoints.

Fax relay rates greater than 14.4 kbps are applicable only to
V.34 / T.38 fax relay. For non-T.38 V.34 supporting devices,
configuration greater than 14.4 kbps is truncated to 14.4
kbps.
Enables Error Correction Mode (ECM) mode during fax relay.

[0] Disable

[1] Enable (default)
Determines the coder used by the device when performing
fax/modem bypass. Typically, high-bit-rate coders such as
G.711 should be used.

[0] G.711Alaw= (Default) G.711 A-law 64
[1] G.711Mulaw = G.711 µ-law

Defines the number (20 msec) of coder payloads used to
generate a fax/modem bypass packet.
The valid range is 1, 2, or 3 coder payloads. The default is 1
coder payload.
Determines whether the device sends RFC 2833 ANS/ANSam
events upon detection of fax and/or modem Answer tones (i.e.,
CED tone).

[0] = Disabled (default)

[1] = Enabled
Note: This parameter is applicable only when the fax or modem
transport type is set to bypass or Transparent-with-Events.
Defines the fax bypass RTP dynamic payload type.
The valid range is 0 to 127. The default is 102.
Defines the modem bypass dynamic payload type.
The range is 0 to 127. The default is 103.
Defines the fax gain control.
The range is -18 to -3, corresponding to -18 dBm to -3 dBm in 1-
dB steps. The default is -6 dBm fax gain control.
Defines the fax bypass output gain control.
The range is -31 to +31 dB, in 1-dB steps. The default is 0 (i.e.,
no gain).
Defines the modem bypass output gain control.
The range is -31 dB to +31 dB, in 1-dB steps. The default is 0
(i.e., no gain).
